Photo Gallery

Bolshoi ("Big") Semiachik is a group of Late Pleistocene-Holocene stratovolcanoes and extrusive domes located within a large caldera. The massif is seen here from the western rim of the caldera (Bort ridge). Bolshoi Semiachik (Zubchatka or Zubchatyi) volcano per se is the large Late-Pleistocene edifice on the left-center horizon. Several Holocene extrusive domes and vigorously active thermal fields are located west and SW of the volcano.
